Connect Your SX4e to AC Power
1)A protective earth (safety ground) terminal (screw) marked with this protective earth symbol is provided on the back of the SX4e Phonecell unit. Connect this terminal to a good earth ground (i.e., a cold water pipe) by means of an 18 gauge or heavier insu- lated wire. The wire insulation should be green with a yellow stripe to indicate that this is a protective earth (safety ground) connection - see Figure 5.
2)Connect the Line Cord from the AC power source to the Power Supply.

NOTE: An optional battery back up unit (not supplied) may be used instead of the Power Supply - see Figure 6. Follow the battery installation instructions provided with the Backup Unit.
4)The LED Power Status indicator (located on the front of the FWT) will turn green immediately upon connecting to power.
